58 rare book dealers from Switzerland belong to the Vereinigung der Buchantiquare und Kupferstichhändler in der Schweiz (VEBUKU) or Syndicat de la librairie ancienne et du commerce de l'estampe en Suisse (SLACES). It was founded in 1939 and joined the ILAB in 1948. Current president is Peter Bichsel, Marcus Benz is Vice-President.

ILAB has a long tradition in Switzerland. The first ILAB President was William Kundig. As early as 1952 the 5th Congress took place in Geneva, which is also the legal location of the League, followed by the 25th ILAB Congress and the 8th International Antiquarian Book Fair in Zurich in 1978. In 2012, it was time for the ILAB affiliates to meet in Switzerland again. VEBUKU/SLACES organized the 39th ILAB Congress and 24th International Antiquarian Book Fair with meetings in Lucerne, a book fair in Zurich and amazing excursions to the rich treasures of the Swiss libraries, collections and museums.

The VEBUKU unites people dealing in old and modern prints and drawings, old and rare books, periodicals, manuscripts and autographs. Its aim is to protect and encourage a fair trade based on the experience, the expertise and cultural responsibility of its members. In cooperation with the German Association of Antiquarian Booksellers (VDA) and Antiquarian Booksellers’ Association of Austria (VAO) the VEBUKU organizes annual lectures for rare booksellers, that are held in Germany, Austria or Switzerland.
